PyQt : Creating variables from LineEdit

Question

import logging
import sys
import suds
from PyQt4 import QtCore, QtGui, QtNetwork
from service import Ui_Form
from suds.wsse import *

logging.basicConfig(level=logging.DEBUG)
logging.getLogger("suds.client").setLevel(logging.CRITICAL)
url = "http://xxxxxxxxx:xxxx/services/FireScopeConfigurationWebService/v1?wsdl"
token = UsernameToken("xxx", "xxxxx")
security = Security()
security.tokens.append(token)

client = suds.client.Client(url)
client.set_options(wsse = security)

class StartQT4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_Form()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.createButton,QtCore.SIGNAL("clicked()"), self.create_srv)
        ciEditLine = QtGui.QLineEdit()        #variable 1
        str(ciEditLine.displayText())
        monitorEditLine = QtGui.QLineEdit()   #variable 2
        str(monitorEditLine.displayText())
        bolEditLine = QtGui.QLineEdit()       #variable 3
        str(bolEditLine.displayText())
        ipEditLine = QtGui.QLineEdit()        #variable 4
        str(ipEditLine.displayText())

    def create_srv(self):
        try:
                response = client.service.createConfigurationItem(ciEditLine, monitorEditLine, bolEditLine, ipEditLine)
                print response
        except WebFault, e:
                print e


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())

I am trying to take user input from the 4 LineEdit boxes in my GUI and use them as variables in my function for the web services call. But i am receiving this error.

Traceback (most recent call last):
  File "start.py", line 34, in create_srv
    str(ciEditLine.displayText())
NameError: global name 'ciEditLine' is not defined

ed

This is my first app so go easy thanks.

Any help would be greatly appreciated.

You have to attach you reference to ths widgets to the objects, using self :

def __init__(self):
    ...
    self.ciEditLine = QtGui.QLineEdit()        #variable 1
    ...

Also, you need to pass the text value of the widget, not the widget reference:

def create_srv(self):
    try:
            response = client.service.createConfigurationItem(self.ciEditLine.text(), self.monitorEditLine.text(), self.bolEditLine.text(), self.ipEditLine.text())

Like this these references become attributes to your object and can be referenced later in any method by using self
